Pneumatic/Electric/Lever Operated Cast Type 2PCS Design Split Body Floating Ball Valve

Brief Introduction

Q947 fixed electric ball valve is suitable for two position cut-off and adjustment situations. The connection between the valve and the actuator adopts a direct connection method. The electric actuator is equipped with a servo system, without the need for an additional servo amplifier. The operation can be controlled by inputting a 4-20mA signal and a 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, and stable and reliable operation. The actuator can be equipped with electronic electric actuators such as UNIC, PSQ, HQ, DHL, or gas piston actuators such as GTX and AL according to user requirements.

Product Features:

1. Anti-static structure: Trunnion ball  top entry ball is provided with the anti-static structure and adopts the static electricity discharge device to directly form a static channel between the ball and body or between the ball and body through the stem.
2. Double block and bleed ( DBB ) : Both seats hold their respective pressures independent of the body cavity pressurewhich is ideal to verify the sealing of the seats.
3. Trunnion-mounted ball: Features a fixed ball and floating seat rings ,Bearing absorb the side load generated by the pressure acting on the ball.
4. Self-seated valves:In valves designed for standard service, a resilient material is inserted into the metal seat holder to provide a soft-seating acting in addition to the metal -to -metal seating between the ball and seat rings.
